MIAMI — Anti-virus software founder John McAfee's return to the United States marks the latest chapter in a strange, monthlong odyssey to avoid police questioning about a killing in the Central American country of Belize.

The 67-year-old British native was holed up in a hotel in Miami's swank South Beach neighborhood after arriving Wednesday night on a flight from Guatemala, which deported him after he snuck in illegally from Belize. Police there want to question him in connection with the death of a U.S. expatriate who lived near him on an island off Belize's coast.

McAfee says he did not kill the neighbor and feared his life would be in danger if he turned himself in to Belizean authorities. He has not been charged with any crime, and it was unclear whether U.S. authorities had any interest in questioning him.

He was in hiding in Belize for weeks after police called him a person of interest in the killing. Belizean authorities have urged him to show up for questioning but have not lodged any formal charges against him.

In an interview, McAfee told ABC that he'd been faking illness in Guatemala. Asked if his apparent heart problem in court there was a ruse, he said, "Of course. It kept me from going back to Belize."

He said all his money and assets were still in banks in Belize, and he had left Guatemala with just his clothes and shoes. He held up a stack of $5 bills and said a stranger had given them to him after he arrived in Miami.McAfee also said he had made up stories while he was on the run to attract news coverage, although it was unclear what parts of the tale he was referring to.

"What's a better story (than) millionaire madman on the run?" he told ABC.

Reached by telephone at his hotel, McAfee told an AP reporter he couldn't talk because he was waiting for a call from his girlfriend, 20-year-old Belizean Samantha Vanegas. Vanegas had accompanied him when he was on the run, but did not go with him to the U.S.

Other passengers on the flight told the AP that McAfee was escorted off the aircraft before they were allowed to disembark.

"They asked us to please stay seated and said, 'Mr. John McAfee, come to the front,' and he did," said Maria Claridge, a 36-year-old photographer. "He walked very peacefully, chin up. He didn't seem stressed."

Claridge said McAfee appeared to be traveling alone.

"I thought he was either a diplomat or a politician," she said. "It just seemed eerie to be traveling on an airplane with someone who was in trouble."

In Guatemala on Sunday, McAfee said he wanted to return to the United States and "settle down to whatever normal life" he can. "I simply would like to live comfortably day by day, fish, swim, enjoy my declining years."

He later said he also would be happy to go to England, noting, "I have dual citizenship."

McAfee has tried to avoid police questioning about the November killing of American expatriate Gregory Viant Faull, who lived a couple of houses down from McAfee's compound on Ambergris Caye, off Belize's Caribbean coast.

McAfee has acknowledged that his dogs were bothersome and that Faull had complained about them days before some of the dogs were poisoned, but denies killing Faull.

McAfee has led an eccentric life since he sold his stake in the software company named after him in the early 1990s and moved to Belize about three years ago to lower his taxes.

He told The New York Times in 2009 that he had lost all but $4 million of his $100 million fortune in the U.S. financial crisis. However, a story on the Gizmodo website quoted him as describing that claim as "not very accurate at all."
